Calculate the pH at the beginning of a titration of 50.00 of 0.005M HA (Ka=2.0*10^-2) with NaOH solution. If the quadratic equation is assumed to be accurate, what would the percent error in the pH if the simpler (suare root) equation were used to calculate the pH insteac.
Calculate the molar solubility of the following compounds from the Ksp values given, Zn(OH)2
